Board arrive around college with note (9)
I believe the answer is:
committee
'board' is the definition.
(I've seen this before)
'arrive around college with note' is the wordplay.
'arrive' becomes 'come' (coming is a kind of arriving).
'around' indicates putting letters inside.
'college with' becomes 'mitt' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'note' becomes 'e' (musical note).
'come' placed around 'mitt' is 'committe'.
'committe'+'e'='COMMITTEE'
Can you help me to learn more?
(Other definitions for committee that I've seen before include "working group" , "Group delegated to consider some matter" , "Managing group" , "Group of people selected to run things" , "Meeting group" .)
